Research groups have made a breakthrough in the field of hard disk drives (HDD) by demonstrating the feasibility of multi-level recording using a three-dimensional magnetic recording medium to store ...

Microwave-Assisted Magnetic Recording (MAMR) employs a high-frequency magnetic field to lower the effective switching field of recording media, enabling the use of smaller, high-coercivity grains and ...

Scientists have demonstrated a new recording principle that improves recording efficiency by 35% by combining spin torque with conventional heat-assisted magnetic recording (HAMR). This advancement is ...

Use left and right arrow keys to seek audio. We've covered Seagate's HAMR, or Heat-Assisted Magnetic Recording, tech for HDDs, which is set to breathe new life into traditional platter-based storage ...

In a recent article in Acta Materialia authors from Seagate, NIMS and Tohoku University demonstrated two-layer heat assisted magnetic recording. The research team combined experimental measurements as ...

In conventional heat-assisted magnetic recording (HAMR), a laser is used to locally heat the recording medium to facilitate data writing. However, the thermal energy applied is largely dissipated ...

Forward-looking: Magnetic storage technology in hard disks has undergone significant evolution in recent years. Following Perpendicular Magnetic Recording (PMR), Shingled Magnetic Recording (SMR), and ...

Schematic view of (top) currently used HAMR and (bottom) three-dimensional magnetic recording systems. In the three-dimensional magnetic recording system, the Curie temperature of each recording layer ...
